Comment 277 for bug 1189721

According to https://bugzilla.kernel.org/show_bug.cgi?id=84521, there's a kernel module that seems to be working (https://github.com/loimu/rtbth-dkms). I can't test it by myself since I replaced the wireless combo with a Qualcomm-Atheros card.

It's (at least) compatible with most HP laptops and all-in-one desktops. I can understand that a lot of you aren't in the position of buying a new card, but if you're interested here's the datasheet:
